bootm should check before booting the kernel, if the uImage file is OK. If the 
uImage is not OK, bootm should fail.

You can check an uImage in RAM with the "iminfo [address]" command.
Enable the iminfo comamnd with CONFIG_CMD_IMI.

bye,
Heiko

I'm new to U-Boot but on RPi the features are provided by their
proprietary firmware/bootloader.   AFAIK U-Boot doesn't support DT
overlays.

Thank you for this information.

Is there a way to change a loaded devicetree configuration ?

Because we have many boards with small differents. but less memory on disk.
at this time one DTB file need ~150kb. we have 1MB free, but we have  
20 different boards and

every month 1 or 2 new boards.

[U-Boot] use CONFIG_PRE_CONSOLE_BUFFER

2014-08-13 Thread Johann Obermayr 

Hello,

i will use CONFIG_PRE_CONSOLE_BUFFER and have some trouble.


myboard.h
#define CONFIG_PRE_CONSOLE_BUFFER
#define CONFIG_PRE_CON_BUF_SZ4096
#ifndef __ASSEMBLY__
extern char preConsoleBuffer[] __attribute__ ((section(.data)));
#define CONFIG_PRE_CON_BUF_ADDRpreConsoleBuffer
#endif

myboard.c
char preConsoleBuffer[ CONFIG_PRE_CON_BUF_SZ ] __attribute__ 
((section(.data)));



int board_init()
{
.
console_init_f();
.
}

u-boot/arch/arm/lib/board.c
remove console_init_f(); from init_sequence list.

after this changes, u-boot will hang.

use u-boot v2013-04 on arm i.mx6 (Freescale)

Best Regards
  Johann
